Abstract
A video signal compressor includes apparatus for generating motion vectors for respective blocks of video data.
Ones of the motion vectors (other than those which provide direction to co-located blocks in other frames) are determined to be candidates to conversion to vectors which do provide direction to co-located blocks. However, conversion is precluded if the vector is determined to be correlated with one of the neighboring motion vectors.
Ones of the motion vectors (other than those which provide direction to co-located blocks in other frames) are determined to be candidates to conversion to vectors which do provide direction to co-located blocks. However, conversion is precluded if the vector is determined to be correlated with one of the neighboring motion vectors.
